A Secure Authentication System for Controlling Traffic Lights for Ambulances

Abstract

When an ambulance (AMU for short) is going toward a hospital or an accident scene, if there is no traffic control and other guidance supports, due to a traffic jam or other reasons, the AMU may be unable to quickly arrive at the destination. Then, the time at which the hospital can start medically or surgically treating the injured people will be delayed. The earlier the people can be treated, the lower the mortality rate will be. To solve this problem, in this paper, we propose a traffic control scheme, called the AMU traffic control system (ATCS for short) , by which before an AMU passes through a street/road intersection, the ATCS turns the traffic lights to green so that the injured people can be transported to a nearby hospital as soon as possible. While the Regional Transportation Authority (RTA) and AMU communicate with each other, the transmitted messages are encrypted by random numbers and the RSA algorithm. According to our analyses, the system can effectively and efficiently protect the messages delivered through a wireless channel.
